What would you do when a friend online just drops you like a rock for no reason?

Have you ever had someone that you were corresponding with online just quit answering your email or ims? I find this frustrating. There weren't any disagreements or anything. I'm not sure how to respond or should I just move on?

I would just wait it out. You might hear from your internet friend again or you might not. That person probably just has a lot going on in their life right now, maybe their internet is even down. Sometimes I just don't feel like answering e-mails.
